Q166 · Physics

The capacitance of a parallel plate capacitor with air as medium is 6 μ\muF. With the introduction of a dielectric medium, the capacitance becomes 30 μ\muF. The permittivity of the medium is :

(ϵ0=8.85×10−12\epsilon_0 = 8.85\times10^{-12} C2^2 N−1^{-1} m−2^{-2})

  1. 10.44×10−130.44\times10^{-13} C2^2 N−1^{-1} m−2^{-2}
  2. 21.77×10−121.77\times10^{-12} C2^2 N−1^{-1} m−2^{-2}
  3. 30.44×10−100.44\times10^{-10} C2^2 N−1^{-1} m−2^{-2}Official answer
  4. 45.00 C2^2 N−1^{-1} m−2^{-2}
